Summary: CalCOFI 1907BH sailed on RV Bold Horizon at 0800PDT 11 Jul 2019 from 10th Ave Marine Terminal San Diego. 70 of 75 science stations were completed. CTD casts, secchi disk casts, and various net tows were completed at each science station. Underway visual observations of marine mammals and avifauna were conducted while under transit and coupled with sonobuoy deployments at each station. Other underway science included continuous pCO2/pH and meteorological measurements. Unfortunately, approximately 12 hours were lost early in the cruise due to satellite communications malfunction. The ship diverted from the standard CalCOFI cruise track after 93.3 45.0 north to San Clemente Island to affect repairs and resumed work at 93.3 50.0.
